OFFICE-FILE.

SPECIFICATION forming part of Letters Patent No. 516,523, dated March13,1894. Application filed October 3, 1893. Serial No. 487,118- (Nomodel.) Patented in Canada September 15, 1893, No. 44,288.

To all whom it may concern.-

Beit known that LALEXANDER HENRY Cos- TIGAN, of the city of Montreal, inthe district of Montreal and Province of Quebec, Canada, have inventedcertain new and useful Improvements in Office-Files, (for which I haveobtained Letters Patent of the Dominion of Canada under date ofSeptember 15, 1893, under N 0. 44,288,) and I do hereby declare that thefollowingis a full, clear, and exact description of the same.

This invention has reference to office files used for the temporaryreception of papers and has for its object to produce a file which shallbe simple inconstruction and positive in its action.

The invention may be said to consist in the combination with the usualboard and piercing or threading tubes on which the papers are placed, ofa positive lock instead of spring devices and the like for keeping thethreading tubes in their normally closed position.

For full comprehension of the invention,

. reference must be had to the annexed drawings forming a part of thisspecification, in which like symbols denote the same parts and in which-Figure 1 isa plan View of the file constructed according to myinvention; Fig. 2 a plan of under side of plate and Fig. 3 a sectionalview of file.

A is the usual back board on which the file is mounted and B a rigidmetal base plate secured thereto, usually formed with a rim a under itand of some such outline as that shown. In the front or lower part ofthis are set the Vertical threading tubes or wires 0 O carrying thepapers, and in the rear or upper end'are formed journals B, in which isjournaled arocking bar D carrying the bent wires or tubes E E as shownin Fig. 3. From the lower side of this bar D projects a lug or extensionD (usually resting on the board) which, when the bar is rotated passesup through an aperture b in the plate B, but is normally held down so asto keep the ends of the wires E and tubes 0 in close proximity, bydevices now to be described. In the under side of the plate B isarranged aslide F slotted as shown, to engage with and be guided by apin f and having a projection F bearing upon and holding down the lug orextension D. The slide F also passes through a slot a in the rim a ofthe base plate. This arrangement of the extension D and the slide Fconstitutes a positive locking device as compared with those dependentupon the action of a spring to keep the threading tubes together.

The operation of the invention is as follows: The parts being in theirnormal position and it being desired to place on, or take off from, thetubes 0 C, any papers, the slide F is withdrawn, so as to release thelug D" which passes up through the opening I) and allows the bent wiresto be thrown back and papers to be taken off or put on the tubes.

Of course I do not wish to be confined to the connection of the curvedtubes with the rocking bar, as the straight ones C 0 might as readily bearranged to tilt.

What I claim is as follows:

1. In an office file, the combination with a suitable rigid bearingplate presenting fixed journals as shown,-of the stationary and tiltingthreading tubes or wires; a rigid rocking bar journaled at its ends asshown in said fixed journals and carrying the tilting tubes or wires;and a positive rigid reciprocating device for engaging and'positivelylocking said bar in position to close said threading tubes and todisengage and release same.

2. In an office file, the combination with a suitable rigid bearingplate presenting fixed journals B',of the stationary and tiltingthreading tubes or wires; a bar, carried in said journals as shown,having a lateral extension and carrying the tilting threading tubes orwires; and a positive rigid reciprocating locking device for engagingsaid lateral extension and thereby holding such bar in position, toclose said tubes or wires or for disengaging same and releasing the barto open or disconnect such tubes or wires, all as herein set forth.

3. In an office file, the combination with a bar, journaled in the baseplate and carrying the tilting tubes or wires,of an extension from suchbar and a slide for engaging such extension, for the purposes set forth.

4. The combination of plate B having journals, rocking bar D journaledin same, and carrying the tilting threading tubes, stationary threadingtubes carried by said plate, an

extension D from said rocking bar, and a slide as F suitably held inplace and adapted to engage said extension D for the purpose set forth.

5. In an office file, the combination with a suitable fixed base platehaving rim (1, slot at and carrying the stationary threading tubes andpresenting fixed jonrna1sB',-of the rigid rocking bar D, carrying thetilting threading wires, journaled at its ends, in said fixed IOjournals as shown, and having lateral extension D, a slotted slide as Fhaving projection F, and pin f substantially as shown and described.
